I should ahve figured out that you would need to file the slots but I could not fathom the point of an adjustable nut other than the convenience of not having to file the slots.

The screws turn very easily thus when you bend a note around the fift fret or lower the screws turn and they dont always go back and the intonation goes out a little. Not really noticeable as I play but annoying when tuning.

Also when tuning, unless your string line to headstock is a dead straight line of sight then the screws will turn as well, placing them back makes tuning lengthy and annoying if you want to get to 0 cents.

Ill stick with stationary nuts.The features are great, allowing an adjustable height as advertised.

I give this a 10 BUT BEWARE you need to file the slots on this just like a regular nut which completely defeats the purposes above for me. The slots DO have a V shape, as they should, to hold the string properly, however it is the same size across all 6 slots. The low E and A strings do not stay in the slots and the low E kept falling off the fingerboard. I had to raise the High E and B strings more than I wanted becasue they sat flat in the slot otherwise.

The slots need to be filed larger thus making the nut useful for only one guage of string, defeating the point of an adjustable nut.The quality is great. The screws are smooth and held up to repeated fittings and abuse as I tried to figre out how I would use the nut, if at all. It gets a 9 only becasue the screws protrude thru the bottom when down all the way, so much so that you will need to drill small holes into the wood to make room if you want full motion of the screws throw. This was the deal breaker for me as I couldnt get enough depth without drilling holes which I refuse to do. I will just get a solid brass nut and file the slots since you will need to file this nut's slots anyway.
